i was talking to a builder he was telling me even if i build my lsvtec right its not going to be a good daily driver. he also said the compression i was using needed a stronger cam . i am currently running ctr pistons,ctr cams, stock valvetrain, jdm itr headers, full catback with highflow cat, aebs manifold , endyn girdle , arp rod bolts, shot peened rods , gsr trans, 65 str tb 12:1 compression with a p28 custom 4 programs ne body else running this specs on cast pistons how long how many miles ne problems i use 94 octane gas . is this streetable and if now how long i know i need to retard timing

 

if built right, it should last a good lifetime... granted maybe not as reliable as a stock gsr motor, but definately still reliable. it wouldnt hurt you to run bigger cams, but then again you have stock valvetrain. When you were building your motor, you should have installed some aftermarket rods and aftermarket pistons, to lighten up the rotating assembly, which would increase your "reliability". o well. I just mentioned that since LS arent meant to rev to 8000 rpms, and if you wanted to, lightening up your rods and pistons will help significantly.
Just curious, is the engine builder that says its not reliable the one that built it?

regarding your timing, if you are running a high compression motor, I find that it is best to run an ecu program that has STOCK ignition maps, other wise you'll be detonating like a biatch. If you a stock ECU, around 16 degrees of ignition timing should be good, and you can test if it is too much or not by putting your car in 5th gear going 40mph and punching it 50% throttle.. If you do not hear any pinging, you're okae.. if you do, then your compression is too high for dailiy driving. that or you need higher octane gas. You can also lower your compression, but..... the car wouldnt run right.

 

no that guy is not the builder i went with that compression cause i wanted to stay all motor yes the ecu does have some stock programs 4 total 2 racing 2 stock

 

If built right it will last awhile. Also, depends on how you treat it. :D

Since Rod/Stroke ratio is out of wack (ie: putting more force on the cylinder walls) I read that OEM ITR/CTR pistons are actually a good choice. They are cast pistons that put less friction on the walls and coated with a black dry film lubricant on the skirts

 

i know its built right cause i watched them do it i did not skimp on ne thing and i don't shift late unless i am @ the track or racing ie redline i always shift early

if yours is an Auto .. you need to leave the shifter in 3rd the whole time .. and just at the line .. hold the brake down and rev it up a little then release and punch it

 

check out the huge thread that skribblah created about how exactly LS vtecs screw up, read the thread, learn from peoples mistakes.

 

if its build right it will last just as long as any other motor

 

i have read that thread even saves it to my computer its gsr tranny 5 speed
